Dialer Component
The dialer component contains DNIS groups and is responsible for configuration, and maintenance of
counters and statistics. The resource-pool component is responsible for the following:
• DNIS number statistics or counters
• Configuring DNIS groups
Resource Group Manager
Resource groups are created, maintained, allocated, freed, and tallied by the resource group manager.
The resource group manager is also responsible for service profiles, which are applied to resources at
call setup time. The resource group manager is responsible for:
• Allocating resources when the profile has been authorized and a valid resource group is received
• Statistics or configuration of resource groups
• Configuring or applying service profiles to resource groups
• Collecting DNIS number information for channel-associated signaling calls
Signaling Stack
The signaling stacks currently supported in resource pooling are CAS and ISDN. The signaling stack
delivers the incoming call to the resource-pool dispatcher and provides call-type and DNIS number
information to the resource-pool dispatcher. Depending on configuration, call connect attempts may fail
if the signaling stacks do not send the DNIS number and the call type to the resource-pool dispatcher.
Call attempts will also fail if signaling stacks disconnect prematurely, not giving enough time for
authorization or resource allocation processes to complete.
Therefore, investigate the signaling stack when call attempts or call treatment behavior does not meet
expectations. For ISDN, the debug isdn q931 command can be used to isolate errors between resource
pooling, signaling stack, and switch. For CAS, the debug modem csm, service internal, and
